The paper

G. Aslanyan & A.V. Manohar, The Topology and Size of the Universe from the Cosmic Microwave Background, JCAP 06 (2012) 003, arXiv:1104.0015,

uses the 7-year WMAP data. Has any additional checking been done on newer data (e.g. Planck)? Has other work superseded this result, through criticism or improved calculations?

  • $\begingroup$ I think that Planck data did not changed so much the situation. Anyway, I wait for answers to your question. $\endgroup$ – Rexcirus Jan 5 '15 at 22:09

The latest constraint on the curvature of the universe comes from the Planck Mission which indicates that the universe is very flat today.
